If you have not yet invested "heavily" in your relays, maybe looking in a different direction sometimes help

I can't resolve how to ask the person, so here goes: (From the page) ` Models supported: HW-348 HW-343 HW-341 Models with USB-Relay-1, USB-Relay-2 or USB-Relay-4 printed on the PCB ` Looking on the interweb, I find this (as example) [USB HID relay boards](https://www.banggood.com/search/usb-hid-relay.html?from=nav) But I am not sure if they are compatible. I've opened one of the boards and read the specs, but can't find if they are HW-348 (etc) drivers (what ever). Just asking. Thanks.

Such relay boards mentioned are so cheap and can be controlled directly from NR, no need for Arduino and complex buffer coding

Then interacting with HA would be so simple, just use MQTT between NR and HA
